@sdszhang is this seen only on chassis or on pizza box devices as well? Could you please confirm if you are working on this?

@sdszhang is this seen only on chassis or on pizza box devices as well? Could you please confirm if you are working on this? @prabhataravind I'm suspecting it's on chassis only. Didn't see it being reported on pizza box for the same test. Going to work on this issue next week to see if it's sonic repo issue or vendor issue.
